Packaging & Availability
- Packaging and Storing
Packaging
The product is supplied in iron drums (10 kg); plastic drum (25 kg); iron drums (60 kg).
Storing
Polyisocyanates react with water, including atmospheric moisture, with formation of carbon dioxide, which can cause too high pressures in closed containers and form solid insoluble polyureas, which can block pipes, valves, etc. Product must be stored in well sealed original containers, far from any fire sources, at temperatures between 0°C and 30°C. Opened drums must be protected from moisture penetration (use silica gel drying tube or nitrogen atmosphere systems). Use within 12 months from production date (unopened and in the original packaging).
Storage & Handling
- Shelf Life
- 12 Months
- Handling
In solvent borne primers: add 4.5 -14 % of CURING AGENT P 65 referred to total solids.
In natural rubber (as our TACKSOL series) or acrylic solvent borne adhesives: add 1.5-4.5% of CURING AGENT P 65 on the total solids of the adhesive.Add CURING AGENT P 65 to polymer/solution and properly stir to complete dissolution. Compared to other isocyanates dissolved in aliphatic/aromatic solvents, this innovative product presents a longer pot-life.
Considering that crosslinking mechanism depends upon different parameters, such as adhesive concentration, amount of crosslinker, temperature, we suggest checking the curing conditions in advance, in order to avoid spoiling material.
